About Staging Lung Cancer

Welcome to the Staging Lung Cancer Web site, featuring the Staging Calculator, an interactive tool designed to address the complexities of the 7th edition lung cancer stage classification system in a clinically relevant format. The Staging Calculator builds on information from the International Association for the Study of Lung Cancer, the International Union Against Cancer, and the American Joint Committee on Cancer by coupling classification information with a library of images that provide a more thorough understanding of the nuances of this disease.

Using the Calculator

The Staging Calculator on this Web site can be navigated by using the pull-down options in the top red bar to select specific TNM values. After selection, click "View Details" to calculate the specific stage and view related images from CT Scans, PET Scans, endobronchial ultrasounds, and more. The Staging Calculator can also be used by rolling over different areas of the grid and click on the individual fields.

An Overview Grid is also available to provide a quick reference guide.


While the Staging Lung Cancer Web site was developed to aid clinicians in defining a patient's clinical or pathologic state, the Staging Calculator should not be considered a standalone diagnostic tool. Users always are urged to seek out newer information that might impact the diagnostic and treatment recommendations contained within a guideline.
